Floor drain piping ABS or PVC?

[Cannonball]

Hi.

Looking for some more informed information/opinions.

Installing floor drain piping to a centre location in a new slab which will run to a sump outside of the slab for now.
What is best ABS or PVC?
Both will join to a cast iron drain with a rubber coupler so I can use either.
Don't know if I can get Schedule 40 PVC just the lighter stuff that HD has.

Given the fact that ABS can flex a little and is thicker is this better?
What are the negatives on using ABS?

Thanks.

First- is a floor drain allowed? And if so, what type of trap do you plan to use?
What's the deal with cast iron? You can't bury that rubber fitting under concrete.

ABS vs. PVC? And the winner is...

Whichever one is more available.

The use of ABS or PVC is regional, here in CA ABS is what is used, IMO I would use whatever is more common just because in the future one may need parts & the less common may be harder to find in a pinch, ABS is easier to use as it does not require primer & is lighter, but that should not be the deciding factor.

When we install water pipe into new houses pvc is the conduit we run the Blue Ice waterlines through, as abs has flatten on us. Greenghost

Just to be clear the plan is to use a cast flange with a threaded in metal drain.
The flange will be imbedded into the concrete. Thought was that this would be stronger just in case something was rolled over it (jack, sleds, etc).
A Fernco coupler would be used to connect to the ABS or PVC pipe.
As far as I know these couplers can be buried??
I was going to run this to the outside of the slab to a sump.
Not really sure how much I will use the drain, but if needed the sump could be pumped out if needed and would act as a trap to collect dirt.
If it is used lots I could look into tying it to the service later.
As Norcal stated they only seem to use ABS here for basement sump pump drains so kind of question why.

Sorry for the long winded reply, just like to clear this up for my self and others looking at doing the same. After lots of searching couldn't see why one is used over the other.

Just a little advice, try to get as much pitch as possible on that drain pipe. I had the same setup, with very little pitch and it always clogging up with dirt and grit from the cars mostly in the winter. I was always flushing it out with a garden hose.

Thanks will keep that in mind.
Do you feel that greater than the standard 1/4" per foot is required?

Plan on having a way to deal with fuel/oil that may get spilled down the drain.
For this reason a lot of areas won't allow floor drains in garages.

I would not use a Fernco coupling in a non-accessible location, a No-Hub band would be better.

Thanks.
Will see if I can find that clamp fitting.
I have used the Fernco in the past but this was in a location that could be dug up if ever needed.
Thought was that the sump outside of the building would act as containment if anything was ever to leak.

I remember years ago when I placed floor drains into my new house garage, the plumbing inspector (new to the area from a larger centre) only concern was with the storm water backing into the garage.
His take on it was that if your vehicle was to leak fuel or oil on the street it would be no different then if it was in your garage.
Still like the idea of a containment sump as sometimes accidents happen.

Yep ! Check your local codes first !!

A couple of house ago, I had a floor drain that dumped into a drywell, just a giant hole filled with rock. They wouldn't allow tying into a storm drain or sewer. I've heard of people using a 55 gallon drum as a sump but I think it would probably rust away and collapse. Maybe one of those heavy plastic chemical drums might work but you would have to be able to access it to clean it out once in a while.
